Just post a bit more (precisely)... out of your JPG I can't read how you designed/compiled/filled your report.

my custom data source class:

package wj_XunLian.bean;

import dori.jasper.engine.*;

 

public class XL_t_030_002_12PrintCustomDS implements JRDataSource{

 

public XL_t_030_002_12PrintCustomDS() {

}

 

/*下面的操作是把一些数据组织起来,按照打印的格式组成数组,如果数据量大,对性能的影响我没有进行测试

QuFen在QuFenLine="a"时画线。NianDuXunLianChenJi在NianDuXunLianChenJiLine="1"画线。

XunLianDengJiPingDing在XunLianDengJiPingDingLine="1"时画线。

这个只是一个简单的例子,在实际中要从数据库中或其他的方式,按下面的格式组织数据。

compile and copy XL_t_030_002_12PrintCustomDS.class to iReport0.2.3/classes/classes/wj_XunLian/bean/ folder

my subreport:

connect properties tab:

type of connection/datasoure->CustomJRDSource

Factory class->wj_XunLian.bean.XL_t_030_002_12PrintCustomDS

The static method to call retrive the JRDataSource->getXL_t_030_002_12PrintCustomDS

 

only run subreport is ok!!!

 

my masterreport:

Subreport tab:

Connection/DataSource Expression->Use Datasource expression

input:new wj_XunLian.bean.XL_t_030_002_12PrintCustomDS()

 

now run masterreport:

deplay error.look at it here:

Well,

 

What DataSource do you use for filling MasterReport? Is it the same like you use for your SubReport? And how many times a subreport will called? Once for each MasterReport-Record? Or do you just use the MasterReport for dummygroups and better layout-management?

 

I wouldn't create everytime a new instance of your "XL_t_030_002_12PrintCustomDS" with all your data... everytime the MasterReport calls the SubReport a new instance is created and all the data come again that the previous call of your subreport already listed. Is this what you want?

Or do you want to filter out some records by the subreport that do match some criteria given by the masterreports current record?

my masterreport only one recorder,and masterreport using an empty datasource.in application :

jasperPrint = JasperFillManager.fillReport(jasperReport,parameters,new dori.jasper.engine.JREmptyDataSource());

Well,

 

I can't say more, that you should downgrade your report to a simple design containing one MasterReport with just one SubReport and pass your DataSource and your compiled subreport as parameter when filling your mastereport.

 

So I would try these steps:

 

1.) load MasterReport from XML/InputStream

2.) load SubReport from XML/InputStream

3.) compile MasterReport to a JasperReport-Object

4.) compile SubReport to a JasperReport-Object

5.) fill your JRBeanDataSource for your SubReport (or whatever model you like) into a JRDataSource-Object

6.) put the JRDataSource-Object and your compiled SubReport into a parameter-HashMap

7.) fill your MasterReport-Object with parameter-HashMap and an empty DataSource (JREmptyDataSource)

 

in your XML-desgin you should have two paratemers - one e.g. "paraSubReport" and one e.g. "paraDataSource"

 

and in the DataSourceExpression you should enter the $P{paraDataSource} and in the SubReportExpression you should enter the $P{paraSubReport}

 

and that should work. Also note, that the SubReport is opaque and has the same papersize as the MasterReport and that the margins are ok.

Some people here encountered problems with the defined sizes and overlaying some bands when page breaks etc. - you could search the forum for it.

 

more I can't say - sorry
